This bookmarklet can be used to keep track of global variables attached to window.

It displays the user-defined global variables by comparing all properties attached on current window to all standard properties extracted from an empty iframe.

To install, create a new bookmark in your bookmark bar and copy-paste the contents of listGlobals.bookmarklet

listGlobal.min.js
